FIRE AND WATER PROOF COMPOSITION.

To all whom itrma' concern:

Be it knownthat I, CARL J. PATER, a citizen of the United States, residing at Hartwell, in the county of Hamilton and, State 5 of Ohio, have invented certain ne nduseful Improvements in Fire and lfite r Proof Compositions, of which the fol wing is a specification.

My invention relates to improvements in fireproof and waterproof composition.

The object of my invention is the production of a thoroughly eflicient combined fireproof and Waterproof material or composition, which is particularly adapted for use as a fire and waterproof heat insulation for steam pipes, stack linings, boiler coverings, lining for ocean steamers, heated surfaces and the like.

My invention consists in the composition and in the process of making same as herein set forth and claimed.

Articles of manufacture for insulating purposes made of asbestos are fireproof but not waterproof. The waterproofing %ualities which I impart to manu ac ure articles are the resultant of a chemical comination between magnesium silicate conre gisa-L eg v 350 Ms W en e same are s emperature of from three hundred degrees 300) 0 seven hundred dc eesTlO'OTF ahreneit.

I produce the composition by mixing the following ingredients in substantially the following proportions; Two hundred (200) gallons of 40 Be. sodium silicate with one hundred (100) ga one 0 water. To this resulting diluted sodium silicate is mixed by mechanical agitation or otherwise, one 40 thousand (1000) pounds of ma esium silicate consisting of asbestine din pow ere orm. a ac pro uct 1S esired lam bla k may be added to the above mitur' e.

The manufactured article, consisting of asbestos board, asbestos air cell covering,

pipe covering or other like fire-proof product, is immersed in the above described mix ture, and after draining, is dried out thoroughly in a dry-house or bya'i'l'y'b'ther suitable means. When dry, it is placed in an oven and subjected to a heat not exceedin 7 00 Fahrenheit. DurinW ess a chemical union takes place between the magnesium silicate consisting of asbes- V Specification of Letters Patent.

Patentetlguly 15, 1913. 2 7 k tine and the sodium silicate; thereby producing a sodium magnesium silicate. This forms a compound which is insoluble in lows: sodium silicate plus asbestine equal'si sodiumnmagnesium silicate and water:

The use of sodium silicate alone when coated over the asbestos product will not result in an absolutely water-resisting compound, even when baked at the required temperature since the chemical union between t no su ciently complete and will not resist thmmm The use of asplialts, linseed Oll products, or other water repellent substances will yield a waterproof material, but at the same time, use is made of an inflammable ingredient, and the fireproof quality is thereby destroyed. On the other hand, by the use of my invention, the magnesium silicate consisting of asbestine and sodium silicate being mineral products, are fire roof, and on bakin produce chemically an lnsoluble sodium ma nesium SlllCfitG-W this insoluble silicate in and on the surfaces of the already formed asbestos product which is fireproof, the latter is also made waterproof, thereby forming a combinedfi e roof and waterproof material or article.

y orming a sur ace 0 t e character described upon the asbestos board or other asbestos article, the union of ingredients forming the insoluble sodium magnesium silicate thus heated, also unites, and firmly adheres to the asbestos material. This combination forms a superior product, and one which-may be subjected to water or heat indefinitely, the same being proof against either.

One of the advantages of my composition is the economy in its production.

I claim:

1. A fireproof andv waterproof composition consisting of a union of magnesium silicate asbestine and sodium silicate formed at ill temperature of from 300 to 700 Fahreneit.

2. An asbestos article coated with a waterproof and fireproof compound consisting of a union of magnesium silicate asbestine and sodium silicate formed at a temperature of from 300 degrees to 700 degrees Fahrenheit.

3. The process of making the herein described fireproof and Waterproof composition, which consists in preparing a mixture of water, sodium silicate and magnesium silicate asbestine in powdered form, then im mersing an asbestos article therein, then drying the immersed article, and then subjecting it to a temperature of from 300 to 700 Fahrenheit.

4. The herein described fireproof and waterproof composition, consisting of ingredients in substantially the following proportions: 200 gallons of 40 Be. sodium silicate mixed with 100 gallons of water, and

1000 pounds of magnesium silicate asbes- JAMES N. RAMSEY, WILLIAM J. MOELLER.
